When radiusstyle =`contour', the task calculates the source region shape as an elliptical locus which approximates the contour of the PSF at a given flux value. ... Clearly, in order to calculate the shape of such a flux contour, it is necessary firstly to normalize the PSF to the source brightness and secondly to determine the flux level (in `brightness' units per pixel) at which to find the contour. ...

. Comment on J1239-1023 . No image is shown by Dallacasa et al. (1998) as they did not find the VLBI structure at 2.3 and 8.4 GHz prominent, just dominated by a compact region barely resolved in position angle about -45 . In our case the source is well resolved, with a jet pointing to the W-NW direction, in agreement with what is seen in the images at 2.3 and 8.4 GHz from the VLBA Calibrators database.
